Product Description

SUSE Linux Enterprise Server 12 SP3 is a highly reliable, scalable and secure server operating system for efficiently deploying highly available enterprise-class IT services in physical, virtual or cloud environments. Designed for mixed IT environments, it offers best of breed performance with reduced risk of technological obsolescence or vendor lock in.

SUSE Linux Enterprise Server 12 SP3 is the only Enterprise Linux Operating System currently available to deliver:

  • Robustness on administrative errors and improved management capabilities with full system rollback based on the btrfs filesystem and SUSE's snapper technology, including service pack rollback
  • Unmatched scalability: up to 8192 CPU cores and 64 TiB RAM, support for the XFS filesystem for more than 10 years (see SUSE YES hardware certifications)
  • The only truly integrated local systems management stack on Linux: for interactive use (YaST), scripting (AutoYaST) and integration into multi machine systems management environments such as SUSE Manager.
    In SUSE Linux Enterprise 12 SP3 we are continuously expanding these capabilities via the unique Advanced Systems Management machinery, and KIWI, an open source system to create operating system images for physical deployments as well as provisioning into virtual hypervisor environments, container frameworks (Linux Containers, Docker) and public and private clouds. KIWI is specifically useful for customers who plan to create "golden images" based on SUSE Linux Enterprise.
  • Modern Open Source network management using the event based "wicked" framework, providing Network Configuration as a Service; and Software Defined Networking capabilities.
  • Support for leading hypervisors, powerVM and KVM. Support for Linux Containers integrated into the virtualization management infrastructure.
  • Interactive as well as Unattended upgrade (offline, in place) from the latest SUSE Linux Enterprise 11 to SUSE Linux Enterprise 12 SP3 on all architectures.
  • Integration with the new SUSE Customer Center, SUSE's central web portal to manage Subscriptions, Entitlements, and provide access to Support.

SUSE Linux Enterprise Server provides market-leading usability, seamless interoperability with existing IT systems, and virtualization capabilities as a host and Perfect Guest.

System Requirements

Minimum Linux server system requirements for installation

  • Local Installation: 512 MiB RAM (1024 GiB RAM recommended), 512 MiB Swap recommended
  • 2 GiB available disk space (more recommended, 8.5 GiB for all patterns)
  • 16 GiB for snapshot/rollback of the OS

Recommendations for specific uses

  • 512 MiB to 4 GiB RAM, at least 256 MiB per CPU
  • 4 GiB hard-disk space, 16 GiB for snapshot/rollback of the OS
  • Network interface
  • For print servers - a faster processor or processor share or additional processors to improve server-based printing
  • For web servers - additional RAM to improve caching, and additional processors to improve web application performance
  • For database servers - additional RAM to improve caching, and multiple disks for parallel I/O
  • For file servers - additional memory and disks, or a Redundant Array of Inexpensive Disks (RAID) system to improve I/O throughput

Download and Installation

SUSE Linux* Enterprise Server is available for download for each available platform as two DVD ISO images. DVD1 contains the binary packages, DVD2 the source code:

  • Files with "x86_64" in the name are for the AMD64 and Intel* 64 platforms.
  • Files with "s390x" in the name are for IBM* z System or LinuxONE.
  • Files with "ppc64le" in the name are for the IBM* Power LE platform.
  • Files with "aarch64" in the name are for the ARM 64 platform.
  1. Download the ISO images to a workstation or to a network drive.
  2. Creating DVDs from the ISO images is usually not necessary in your z System or LinuxONE environment.
  3. Review the Deployment Guide for more detailed instructions and deployment options.

Important: Create the DVDs using the contents of the ISO images. Do not create the DVDs by burning the .iso files themselves (i.e. as a single "track") to DVD. Instead always choose "burn image", "burn ISO", "write premastered image", ... or similar.

For example, if you're using Gnome, right click on the ISO file and select "Open with CD/DVD Creator", then click Write.


For quick installation instructions, see the SUSE Linux Enterprise Server 12 SP3 Installation Quick Start, available under the docu directory on the ISO image for DVD1. Or find our documentation available online at the SUSE Documentation pages.

For more detailed installation instructions, see the SUSE Linux Enterprise Server Administration and Deployment Guides available under the docu directory on the ISO images for DVD1, and online as well.
